Embodiment Construction
[0065]The invention will be described, in at least one of its embodiments, with reference to the example of the drilling installation of FIG. 1. In this drilling installation, the pipes according to the present invention are equipped with a large-diameter tubular coaxial transmission line. The invention is of course not limited to this particular example, and may apply to any pipe, which one intends to equip with a data transmission function, in addition to its initial function of conveying substances.
[0066]FIG. 2 is a cross-sectional view of a section of drill pipe 21 including a large-diameter tubular coaxial transmission line according to a particular embodiment of the present invention. As it will be described hereafter in relation with FIGS. 3, 4, and 5, it is proposed to connect two successive large-diameter tubular coaxial transmission lines by means of an electromagnetic coupler. In the example shown, this coupler is in annular form.
[0067]The depicted section 21 includes a p...
